Domine (fish)

Domine is a genus of small, freshwater fish belonging to the family Cyprinodontidae, commonly known as pupfishes. The genus is endemic to specific regions of Madagascar, found in isolated bodies of water such as marshes, springs, and streams.

Domine pupfishes are characterized by their small size, typically reaching a maximum length of only a few centimeters. They exhibit a flattened head and a dorsal fin positioned far back on the body. Coloration varies between species, often displaying iridescent or metallic hues.

These fish are adapted to survive in harsh environments with fluctuating water levels, high salinity, and extreme temperatures. They are omnivorous, feeding on algae, small invertebrates, and organic detritus.

Due to their limited distribution and sensitivity to habitat changes, some Domine species are considered threatened or endangered. Conservation efforts are focused on preserving their natural habitats and preventing further degradation of their freshwater ecosystems.

The genus Domine is of interest to researchers studying evolutionary adaptation and biogeography, particularly in island ecosystems like Madagascar. Their unique adaptations to challenging environments make them valuable subjects for understanding the resilience of fish populations in the face of environmental change.
